SIGSEGV when getting string from NSLocalizedStringFromTable

I am getting a strange crash sometimes when getting a string from NSLocalizedStringFromTable. Here is the relevant section of my crash's stacktrace:

CoreFoundation                      0x33c4b7f7 CFEqual   98
CoreFoundation                      0x33cf6a14 __CFBasicHashStandardEquateKeys   20
CoreFoundation                      0x33cf8770 ___CFBasicHashFindBucket_Linear   224
CoreFoundation                      0x33c4b654 CFBasicHashFindBucket   228
CoreFoundation                      0x33c4d4a1 CFDictionaryGetValue   56
CoreFoundation                      0x33c528f5 CFBundleCopyLocalizedString   104
Foundation                          0x32e6ab67 -[NSBundle localizedStringForKey:value:table:]   30
MyApp                          0x000270eb MyApp   155883

The code which causes this is:

NSMutableArray* tableListOptions = [[NSMutableArray alloc] initWithCapacity:1];
[tableListOptions addObject:NSLocalizedStri开发者_开发技巧ngFromTable(@"My String", @"MyTable", @"")];

Any suggestions as to what might be causing this crash? I use NSLocalizedStringFromTable all the time throughout my app but this location seems to be causing problems, though I am having trouble duplicating the crash consistently.
